[Qgis-user] size-scale field option missing in style >> advanced

[Barry J Kronenfeld]

Hi,


I'm trying to create a symbol map from a point shapefile using color for one field and size for the other. I see many websites explaining how to do this using the "Size-Scale Field" option under the Advanced button in the Style selector, e.g.


http://qgis.spatialthoughts.com/2012/02/styling-vector-data-in-qgis-using-size.html


The problem is, I don't see that option in my version of QGIS (Pisa). Am I missing something? Has anybody else experienced this?


Thanks,


Barry
